Poverty Indices Revisited

Multidimensional poverty indices

This paper explores the axiomatic foundation of multidimensional poverty indices. Departing from the income approach which measures poverty by aggregating shortfalls of incomes from a predetermined poverty-line income, a multidimensional index is a numerical representation of shortfalls of basic needs from some pre-speci®ed minimum levels. The class of subgroup consistent poverty indices introd...

Pulsar Braking Indices Revisited

Using the standard equation for the slowdown of a neutron star, we derive a formula for the braking index via integration rather than the conventional differentiation. The new formula negates the need to measure the second time derivative of the rotation frequency, .. ν. We show that the method gives similar braking indices for PSR B1509– 58 and the Crab pulsar to those already in the literatur...

Perfusion indices revisited

Monitoring of tissue perfusion is an essential step in the management of acute circulatory failure. The presence of cellular dysfunction has been a basic component of shock definition even in the absence of hypotension. Monitoring of tissue perfusion includes biomarkers of global tissue perfusion and measures for assessment of perfusion in non-vital organs. The presence of poor tissue perfusion...

Robustness Properties of Poverty Indices

Drawing on recent work concerning the statistical robustness of inequality statistics we examine the sensitivity of poverty indices to data contamination using the concept of the influence function. We show that poverty and inequality indices have fundamentally different robustness properties, and demonstrate that an important commonly used subclass of poverty measures will be robust under data...
